This is a much bigger deal than most people realize.
Poor schema design will cause your system to choke

That certainly has a lot of support in the scientific community

physics.

Oh, just a small note on this topic...
Lacing (or even zip tying) doesn't really help a great deal for
tracability and whatnot unless you at least do a rough job of combing
out cables. In fact, failing to do so when you're tying cables down
can kink cables and actually lead to failures since
